A heroic raider with your progression shouldn't need personal recommendations for gear/spec/talent. If anything , raiders of such progression are theorycrafting themselves anything they need. It would be completely different if you had done the work and calculated what would be best for your character then posted your findings for discussion.

Trying to decide on talents/build(stack stam, haste, mastery, avoidance, etc) for heroic Sha 25. Would love any input you may have. Our other tanks seem to be focusing on avoidance/stam, not sure what we should be doing as paladins.
